The invention discloses a counterweight fixing device and a counterweight fixing device set. The counterweight fixing device comprises a bridge plate and a counterweight, wherein a sliding rail is arranged on the bridge plate, the sliding rail extends from the rear bridge end of the bridge plate to the middle bridge end of the bridge plate, a sliding block is mounted on the sliding rail in a sliding mode, a plurality of sets of evenly-distributed threaded holes are formed in the two sides of the sliding rail, a mounting plate is integrally arranged at the top of the sliding block, and a mounting column is integrally arranged at the top of the mounting plate; and the counterweight is composed of a plurality of counter balances, through holes are formed in the middles of the counter balances, and the counter balances sleeve the mounting column through the through holes. According to the counterweight fixing device, the sliding rail leading to middle bridge along a rear bridge is arrangedon the bridge plate of a crane, a counterweight mounting seat is mounted in the sliding rail in a sliding manner, the counterweight slides to the rear bridge to balance the weight of the crane when the crane works, and the counterweight slides to the middle bridge of the crane when the crane moves, so that the gravity of the crane is balanced, and the movement is not influenced.

    本发明公开了一种平衡重固定装置及平衡重固定装置组,包括桥板和平衡重,桥板上设置有滑轨,滑轨从桥板的后桥端延伸到桥板的中桥端,滑轨滑动安装有滑块,滑轨的两侧设置有若干组均匀分布的螺纹孔,滑块的顶部一体化设置有安装板,安装板的顶部一体化设置有安装柱;平衡重由若干块平衡块组成,平衡块的中部设置有通孔,平衡块通过通孔套装于安装柱上;本发明在起重机桥板上设置有沿后桥通往中桥处的滑轨,将平衡重安装座滑动安装于滑轨内,当起重机工作时将平衡重滑动到后桥位置,平衡起重机重量,当起重机移动时,平衡重滑动至起重机中桥处,使起重机重力平衡,不影响移动。
